Automate Save State Feature in Firemonkey

One of the many exciting new features of Delphi XE7 is the Save State in Firemonkey.
The FireMonkey Save State feature allows you to save data describing the state of the application before it closes. The Save State data can be used to recover the state after the application is restarted.
This is a very cool feature but the way in which you save and restore the data is not so refined (for more info see this ).
What happen if I need to save 10,15 or more components? I need to specify the save and the restore for each one.
So I decided to write a class helper to automate this process!
Using JSON serialization all the components of type TFMXObject are saved. In particular is stored the Data property.

You can find the demo in my github repository .

This is a snippet of the demo

uses SaveStateHelper;

procedure TForm1.FormCreate(Sender: TObject);

procedure TForm1.FormSaveState(Sender: TObject);

I hope you enjoy it!!
